SOAP-DISPENSING MACHINE.

Specification of Letters Patent.

Application filed March 13, 1912. Serial No. 683,495.

To all whom it may concern:

Be it known that I, HENRY R. EVANS, a

citizen of the United States, and a resident of New York city, county and State of New York, have invented certain new and useful Improvements in Soap-Dispensing Machines, of which the following is a specification.

My invention relates to improvements in dispensing machines, and more particularly to soap dispensing machines, in which a cake of soap is granulated or comminuted when desired for use.

One object of my invention is to provide a machine which is simple-and efficient in construction and operation, and economical in manufacture and use.

A further object of my invention is to provide a machine in which the soap may be positively fed with respect to the cutter or granulating means, and at a properly reduced speed with respect to the rotation of the soap, andin which the means for accomplishing this is simple and efficient, and conveniently placed within the apparatus, and in which a follower is provided for the soap, which follower carries the speed reducing means for positively feeding the soap.

A further object of my invention is to provide a simple and efiicient means for locking parts of the apparatus together, whereby they may be quickly taken apart for the insertion of new cakes of soap or other material.

A further object of my invention is to provide a new form of feeding device which may be quickly disengaged so as to allow the quick refilling of the apparatus with fresh soap.

Further objects, will more clearly features and advantages appear from the detailed description given below taken in connection with the accompanying drawings which form a part of this specification.

In the drawings, Figure 1 is a vertical section through a machine embodying my invention in one form. Fig. 2 is a front view of the machine shown in Fig. 1. Fig. 3 is a sect-ion taken on the line III-J11 of Fig. 1. Fig. 4 is an elevation of the follower of the machine shown in Fig. 1. Fig. 5 is a section taken on the line V-V of Fig. 1. Fig. 6 is an end view of a cake of soap such as may be used in my improved machine. Fig. 7 is a side view of such a cake of soap. Fig. 8 is a section taken on the llne YIIIVIII of Fig. 1. Fig. 9 is a similar v ew, but showing'the split nut in closed positlon. Fig. 10 is a detailed view of the device for locking the cutter head in position'. Fig. 11 is a detailed section showing the key in conjunction with the locking de .vice. Fig. 12 is a section of the key, taken on the line XIIXII of Fig. 11.

Referring to the various-figures, 1 represents a suitable frame comprising a cylindrical container 2. -At the front of the frame or container 2 is a cutter head 3 provided with suitable cutting means or knife edges 4, with apertures 5, so as to form a suitable cutter or granulating means for the machine. The cutter head 3 is provided with a flange 6 adapted to be inserted in the member 2, which flange is provided with notches 7 adapted to cooperate with pins 8 fixed to the cylinder 2 in order to form a bayonet joint to secure the cutter head 3 to the fixed frame of the machine. The flange 6 is provided with a recess 9 at its top into which is adapt- ,ed to slide the end of a sliding locking member 10. The sliding locking member 10 is guided 1n its movement by a guide 11 rigid with the cylinder 2, and is provided with a depressed arm 12 sliding in a guideway 13 rigid with the frame of the machine. A U shaped slot is provided at 14, on the frame of the machine, into which is adapted to be inserted a key 15 of similar shape, which key is provided with beveled edges 16 adapted to cooperate with the face 17 on the arm 12 in order to force the arm and member 10 1 to the left, as shown in Fig. 1, against the action of a spring 18. I

19 represents a screw threaded shaft passing centrally through the apparatus and centrally through the soap 20. Screw threaded upon the right hand end of the shaft is an extension 21 provided with an integral head 22. Journaled about the extension 21 is a crank handle 23 provided with a spring pressed pin 24 adapted to engage a depression 25 to form a pawl and ratchet arrangement, whereby when the handle 23 is turned in a clockwise direction, as seen in Fig. 2, it will cause the shaft 19 to be likewise rotated, but when the handle 23 is turned in the opposite direction the pin 24 will slip over the surface of the extension 21, and thus will notcause rotation of the Patented July 11, 1916.

shaft 19. At one end the shaft 19 or the extension 21 is journaled in bearings at 26,

and at the other end in bearings at 27. The screw threaded shaft 19 is provided with two longitudinal slots 28, one directly opposite the other. Fitting in these slots are arms 29 integral with a member 30 forming part of a follower for the cake of soap 20. Rigidly secured to the member 30 and forming part of the follower, is a sheet metal member 31 provided with suitable depressions 32 stamped therein which are adapted to engage with corresponoing depressions 33 in the face of the cake of soap 20. The member 31 is also provided with an integral flange 34 adapted to engage the periphery of the cake of soap and hold it in proper alinement. A washer 35 is placed between the member 31 and the member 30, but all three parts are rigidly secured together by locking projections 36 (see Fig. 4). Rigidly secured to the member 30 is a gear 37. Loosely journaled upon the member 30 is a rotating member 38 having rigidly securel thereto a gear 39.

Loosely journaled about the members 30 and 38 is a hollow casing 40 made of two members secured together, as by peripheral flanges. Journaled in the casing 40 are two pairs of gears 41 and 42, the gears of each pair being secured together by pins- 43. ()ne each of the gears of these pairs 41 and 42 mesh respectively with the gears 37 and 39 (see Figsl and Also journaled in the casing 40 are two pairs of gears 44 and 45, which may or may not be rigidly connected together. The casing 40 is prevented from rotating with respect to the frame and cutter by means of a projection 46 which comes against the sliding member lO-which acts as a stop therefor. The gear 39 is provided with two teeth more than the gear 37, while the gears of the pairs 41, 42 and 44, 45, are all provided withthe same number of teeth.

Pivotally mounted. on the member 38, at 47 and 48, are two parts 49 and 50 forming a split nut 'with threads adapted to cooperate with the screw threads upon the shaft 19. These parts 49 and 50' are normally pressed apart by means of springs 51 (see Figs. 8 and 9). Loosely journaled about the member 38 is a dished shaped member or casing 52 provided with depressions 53 therein. Extending between the depressions 53 and the parts 49 and 50, are links 54 and 55 so arranged that when the member 52 is turned in one direction the links 54 and 55 will force the parts 49 and 50 toward one another in order to cause their screw threads to come into operative engagement with. the threads of the shaft 19, and when the member 52 is turned in the opposite direction the parts 49 and 50 are released and forced away from one another by the springs 51 so that the split nut is quickly disengaged from the shaft 19. Theparts 49 and 50 are provided with pins .56 operating in slots 57 which limit the movement of the members between predetermined limits, and also assist the springs 51 when members 49 and 50 are caused to recede.

The operation of the machine will be clear from the following: Assuming the parts to be in the position shown in Fig. 1, then when handle 23 is turned in a clockwise direction the shaft 19 will be likewise rotated. thus causing the rotation of the parts 30 and 31, because of the arms 29 extending into the slots 28 in the member 19. The follower 31 being locked with the soap 20 by its interlocks 32, will cause rotation of the soap 20 with respect to the cutting edges 4, so that the soap will be comminuted and dispensed through the openings 5.

It will be seen that the member 31 while being rotated by the shaft 19, is nevertheless allowed free longitudinal movement with respect thereto. Rotation of shaft 19 and member 30 causes rotation of the gear 37, which in turn causes rotation of the pairs of gears 41 and 42, having their axes fixed with respect to the frame, by means of the projection 46 engaging the sliding member 10. Rotation of the gears 41 and 42 causes rota tion of the gear 39, but at a slightly different speed from the speed of rotation of the gear 37, because the gear 39 has two more teeth than the gear 37. Thus I have provided a differential earing or reducing gearing by means of which the member 38 is caused to rotate very slowly with respect to the shaft 19. This slow rotation of the member 38 which carries the split nut, causes the nut to slowly feed its way longitudinally along the shaft 19 so that the follower and all of the other cotiperating parts are slowly fed forward in order to positively feed the soap toward the cutter head 3.

If now it is desired to insert a new cake of soap the key 15 is inserted in the opening at 14, thus withdrawing the sliding member 10 against the action of the spring 13, from the cutaway portion in the flange 6 of the head 3, so that the head 3 may be slightly turned in order to unlock the bayonet joint at 7 8, so that the head 3 and all of the parts carried upon the shaft 19, may be easily removed from' the frame, or cylindrical containing member 2. The circular member 52 is then given a slight turn with respect to the remaining parts of the apparatus so that the links 54 and 55 allow the parts 49 and 50 to be separated under the action of springs 51. This clisen 'ages the split nut from the shaft 19, so that all of the follower parts may be readily slipped ofi of the shaft 19, the arms 29 of the member 30 sliding over the left hand end of the shaft 19 along the slats 28, as will be readily seen from Fig. 1. A new cake of soap may then be slipped over the shaft 19 and into engagement with the re means of the interlocks 33 thereof and the follower parts again placed in position, the split nut closed, as shown in Fig. 9, then the parts inserted in the frame of the'machine and locked therein, as'already described. By

the means described this operation may be done in a minimum amount of time and with great ease and simplicity. It will be seen that in the embodiment shown the reducing gears are carried along with the follower and are very compactly and simply arranged within the apparatus, thus insuring long life to the apparatus, and ease of manufacture.

At I show a beveled button (see Fig. 3) which is resiliently pressed inwardly by means of a leaf spring 61 secured to the inside of the flange 6 of the cutter head. When the cake of soap has become nearly exhausted the button 60 will engage three openings 63 in the flange 3st of the follower as the follower revolves, thus causing a loud clicking noise which serves as a signal or notification that the machine should be refilled.

By arranging the cylindrical container 2 horizontally and having a dished cutter head fixed to the end on which is the handle 23, drip from the hand of the operator does not fall upon the device. Furthermore, it will be seen that the container 2 is closed to the outside atmosphere except at one end and this is closed by the cutter head 3 except for the small cutter openings 5 which are closed by the soap itself. This is important, since in rooms where the humidity is high the soap will become slimy if not substantially closed to the outside atmosphere. This has been a detriment in prior machines. Furthermore, it will be noted that the soap immediately after being cut drops directly into the hand of the operator, and does not have to go through any passageway before reaching the hand, which passageway would become clogged by the granulated soap.

This improvement is largely brought about by having the cutter head dished and projecting fro-m the end of the container. Since the feeding mechanism is all carried by the shaft 19 it is easily removed for repair, etc.

Although I have described my improvements in great detail and with-respect to one particular embodiment of the invention,

nevertheless I do not desire to be limited to such details except as clearlyspecified in the appended claims, since many changes and modifications may well be made without departing from the spirit and scope of my invention in its broadest aspects.
